eperetion are concerned.

This invention has for an object a type of enhances are avoided.

s emergency seat is characterized by llewing features:

. spindle or sup ort mounted on a cane and pivot permitting the pivotingof this spindle and to permit of the emergency being folded forward forconcealing it or putting it out of the way.

2. A. device for adjusting the horizontal projection of the seat.

3. A. brake device preventing the emergency seat accidentally turninhorizontally under the action of the re ing motion of the car when it isplaced facin forward, that is to say in the longitudina direction of"the car.

' The advantages of this system of pivoting emergency seat are thefollowing:

llts support on a spindle and a cone as well the displacement of itsseat allows of the seat being folded into a minimum space. It may rovidean emergency seat pivoting in at any irection, in closed cars smalldimensions and particularly in cars with a cab lit permits also inclosed cars, owing to the ease with which it is concealed or put out ofthe way, the arrangements of a front window glass falling completely andvertically in its recess or casing.

The displacement of the seat from the rear the front allows moreover, ina closed car, a tee passengers seated on the rear seat to go c" 1L thecar without puttin the emergency see out of the way and wit outcompelling th .sengers seated on the said emergency a to get out of thecar. system of emergency seat is also appri. I so the construction ofall seats which 7 a rapidly displaced, particularly r oces, draughtsmanseats, etc. it is possible to cause the emerpivot in all directions, thepasse c l g sted.

As illustrated in the drawing, in the sys- 9o tem of emergency seat, thepivot a and the cone (1 of the spindle or support a are fit-Q ted in akind of bearing b provided at the frontwith a slot 6 and, secured underthe floor c of the car in any suitable manner. I J

Besides through the pivot a passes a pin a which prevents it fromgetting out of the bearing, b this pin cam-however, enter into... a slot6 when the spindle a is folded forward. p

This cone and pivot device allows also of causing the emergency seat topivot in the bearing 6. a I

After having passed through the bearing 6, the pivot a passes also throuh a ring 11 rendered rigid with this pivot y the said pin a.

This ring d forms a. artof abrake and. receives, in recesses (1 Its aeach pushed by a spring f in smal cavities g provided "no in a" washer grendered rigid'with a fixed i p casings by a screw it.

f For permitting the adjustment of the for- :ward projection of the seatj,'the head of the spindle a has a notched top member a provided withside slides a on which can move slide-blocks j rigid with the seat 7'. iA stop device constituted by a small stud k pushed by a spring Zarranged'in a recess a of the spindle a maintains the seat 3' at v thedegree of projection which has been given t ereto by entering into oneof a series of cavities j The frame j? of the back of the seat ispivoted on axes 9" so that it can be bent forwardwh'en the emergencyseat is folded.

The arch member of the back of the seat is telescopically arranged, sothat it can be raised or lowered at will. j

Screw sleeves j acting on tubular slotted parts immobilize this archmember in the position given thereto.

When the emergency seat is caused to turn on itself, the pin a movesunder the bearing Z by drawing the movable ring d with it.

For folding this emergency seat forward, it is' first lifted so as torelease the cone a from the bearing 6, this havin for result to causethe upward movement 0 the pin at in the slot 6 of this hearing and torelease the said pin from the. ball brake. This being effected itsuflices to fold the emergency seat forward by causing its spindle a topivot on the pin a During this folding movement,

the pivot a of this spindle inclines in the slot 6 provided at the frontpart of the hearing.

When this emergency seat is folded forupper end of t fixed conicalsocket for receivingsaidpone" part when the seat is in the raisedositlon,

ward, that is to say when it is concealed or .put out of the way, itoccupies the position illustrated in Fig. 4. i

The forms, details, accessories, materials and dimensions of this systemof emergency seat can of course be varied without departing thereby fromthe principle of the invention.

I claim 1. A folding in a vertical .planma seat'support. on'fthe espindle, a seat mounted on said support, a cone parton the spindle,'a
